Last week I bought a gigabit switch to replace my old knackered 10mb hub, the computer i'm using now has a gigabit card built in but my girlfriends PC only had a 100mb network card fitted. I thought upgrading would be a case of simply uninstalling the old network card, plugging the new card (a Linksys EG1032) in and installing the drivers. Then make sure DHCP is enabled so it can pick up an IP from the router and away we go! But instead of being that simple the thing refuses to work. The network lights are on but not flashing and not matter how many times I uninstall and reinstall the drivers / move the card to another PCI slot the card just wont pick up an IP address. It's driving me crackers and my girlfriend has gone off in a huff cos she needed to access her pc whilst connected to the internet to do some college work I've also tried unplugging the new card and putting the old one back but even this now refuses to connect to the network properly!! The PC will ping itself (127.0.0.1) but not any other PC on the network, the PC wont connect to shared drives on other pc's (eg \\Mashrok\C) and i've checked the cable (CAT 6 cable) and it works fine on this PC. I just cant figure out what the problem is!! btw im using an ADSL router connected to a 5 port Netgear Gigabit Switch. Any helpful suggestions or obvious answers will be greatly appreciated.
